High-resolution spectroscopic analysis of four new chemically peculiar stars [PDF]
, 2022 We present detailed chemical compositions of four stars on the first-ascent red giant branch that are classified as chemically peculiar, but lack comprehensive analyses at high spectral resolution.

Multiplicity among chemically peculiar stars [PDF]
Astronomy & Astrophysics, 2002 We present new orbits for sixteen Ap spectroscopic binaries, four of which might in fact be Am stars, and give their orbital elements. Four of them are SB2 systems: HD 5550, HD 22128, HD 56495 and HD 98088. The twelve other stars are : HD 9996, HD 12288, HD 40711, HD 54908, HD 65339, HD 73709, HD 105680, HD 138426, HD 184471, HD 188854, HD 200405 and ...

A spectral atlas of λ Bootis stars [PDF]
Serbian Astronomical Journal, 2014 Since the discovery of λ Bootis stars, a permanent confusion about their classification can be found in literature. This group of non-magnetic, Population I, metal-poor A to F-type stars, has often been used as some sort of trash can for "exotic"

Reddening-Free Q Parameters to Classify B-Type Stars with Emission Lines
Galaxies, 2023 The emission-line B-type stars constitute a heterogeneous group. Many of these stars show similar optical spectroscopic features and color indices, making it difficult to classify them adequately by means of photometric and spectroscopic techniques. Thus,

Most Rotational Variables Dominated by a Single Bright Feature Are α 2 CVn Stars
The Astronomical Journal, 2023 We previously reported a rare class of variable star light curves isolated from a sample of 4.7 million candidate variables from the ATLAS survey. Dubbed “UCBH” light curves, they have broad minima and narrow, symmetrical maxima, with typical periods of ...
